Neither Solaris nor Linux have a good facility (read: sysctl) for detecting
availability of VIS instructions.

ARM accelerations are reading /proc/self/auxv, which may help us as well. Let's
make this code available for other architectures as at least the reading part
is only specific to Linux.

Not sure what to do about Solaris or the BSDs with SPARC ports, though.
